Envy

Envy is one of the most weakening and debasing of all flaws in one's character. It poisons all one's life. It takes the joy out of every experience. It makes a foe out of every one that surpasses us. We are intended to find a large part of our pleasure in the joys and successes of others, and envy transforms all this possible pleasure into wretchedness.
Amos Wells, from Think On These Things

I will try to find contentment in the paths that I must tread;

I will cease to have resentment when another moves a head.

I will not be swayed by envy when my rival's strength is shown;

I will not deny her merit, but I'll strive to prove my own.

From Streams In The Desert By Mrs. Charles E. Cowman
